a tractors 3pt hitch gives you all that without the gauge wheels (some times gauge wheels optional)
1st photo, you can deal with ditches or maintain a dirt/gravel road that has a slant to it, to help shed off water
2nd photo, same as first with rear tilt cylinder, and then able to raise and lower it.
3rd photo, if you wanted a certain grade, and wanted to feather out the dirt as you were going on. this would be it. the 2 cylinders working together would be like adjusting a "top link" on a 3ph hitch. BUT! it does not do angling!
1st photo, i would avoid
2nd photo, if nothing but dirt/gravel driveway
3rd photo, if doing a lot of re-landscaping of property, and trying to get things nice and level.
though with above, i would most likely go straight for a 3ph box blade, and get a TNT (top and tilt) setup for the 3pt hitch (top link, and 1 or both side links, get replaced with hydraulic cylinders), and have everything, and be able to re-use the TNT for other 3pt stuff. and possibly be able to backup with box blade down, to kinda push some light stuff backwards.
